4 # On the handling of kernel options
6 # All kernel options should be listed in LINT, with suitable
7 # descriptions. Negative options (options that make some code not
8 # compile) should be commented out; LINT should compile as much code
9 # as possible. Try to structure option-using code so that a single
10 # option only switch code on, or only switch code off, to make it
11 # possible to have a full compile-test. If necessary, you can include
12 # "opt_lint.h" and check for COMPILING_LINT to get maximum code
15 # All new options shall also be listed in either "conf/options" or
16 # "<platform>/conf/options.<platform>". Options that affect a single
17 # source-file <xxx>.[c|s] should be directed into "opt_<xxx>.h", while
18 # options that affect multiple files should either go in
19 # "opt_global.h" if this is a kernel-wide option (used just about
20 # everywhere), or in "opt_<option-name-in-lower-case>.h" if it affect
21 # only some files. Note that the effect of listing only an option
22 # without a header-file-name in conf/options (and cousins) is that the
23 # last convention is followed.
25 # This handling scheme is not yet fully implemented.
28 # Format of this file:
29 # Option name filename
31 # If filename is missing, the default is
32 # opt_<name-of-option-in-lower-case>.h
